Playgrounds unresponsive on iOS 11.3 beta 2

Hello,


When I launch Playgrounds on my iPad Pro 12.9“ first generation and try to launch, delete or any action, it becomes unresponsive and I have to force quit.

I tried to restart the app, my iPad even remove the app and reinstall it.

Anybody has an idea ? Or the problem is due to this version of iOS ?


Thanks for your help.
